I just discovered -- figured out, really! -- that my mom has been flushing her underwear down the toilet in her assisted living apartment. She has dementia, but this is a new development. I have provided a basket for her for her dirty underwear and other clothes, but it is empty. I told her this simply was not acceptable, that she would cause major harm to the plumbing system, but I'm so afraid she'll continue to do this. I do her laundry for her, and up until now, this has been working. Does anyone have any experience with this or suggestions as to how to prevent her from continuing to do this?
